hello!
2 Subdomain ,Volume force(ff) and volume heat source(h1) are load in fluid domain(slag). if only one Subdomain is load,the result of speed ​​and temperature is what i think right. but, 2 Subdomain are load together, the result is wrong ,why

thanks for any relay!!

------------------
SUBDOMAIN: Subdomain 1
Coord Frame = Coord 0
Location = SLAG
SOURCES:
EQUATION SOURCE: energy
Option = Source
Source = h1
Source Coefficient = 1 [W m^-3 K^-1]
END
END
END
SUBDOMAIN: ff
Coord Frame = Coord 0
Location = SLAG
SOURCES:
MOMENTUM SOURCE:
GENERAL MOMENTUM SOURCE:
Momentum Source X Component = x2
Momentum Source Y Component = y2
Momentum Source Z Component = z2
Option = Cartesian Components

I have no idea what the problem could be. It might be a bug in CFX. Are you using V14 of CFX?

No idea, you would have to report it to CFX to find out. But the first thing they will say is upgrade to the current version - so it is pointless doing anything about it until you update to V14.

Can't you put both sources in one subdomain? Or one as a source in the domain itself and one in the subdomain? Maybe this would fix the problem?
